LTC1559CS-3.3#TRPBF

Battery Management Overview

The LTC1559CS-3.3#TRPBF is a backup battery controller designed for nickel-cadmium cells, housed in a 16-pin SOIC package. It provides a fixed 3.3V output and operates within a temperature range of -40°C to +85°C. The device integrates charge control logic for maintaining standby power in systems requiring continuous data retention or real-time clock functionality.

Battery Management Feature Summary

• Integrated charge management for single-cell nickel-cadmium backup batteries
• Fixed 3.3V regulated output for system support during main power loss
• Compact surface-mount packaging suitable for space-constrained designs

Battery Management Applications

• Real-time clock (RTC) backup power supply
• Static RAM (SRAM) data retention circuits
• Non-volatile memory backup systems

Battery Management Procurement Notes

Verify the specific suffix TRPBF against the official Analog Devices datasheet to confirm tape-and-reel packaging and lead-free compliance. Confirm availability status as distribution channels may indicate limited stock or end-of-life conditions. Ensure the operating temperature range meets the final application requirements before procurement.

Battery Management Selection Notes

Select this component when a dedicated, low-component-count solution for NiCd backup charging is required. It is suitable for applications needing a stable 3.3V rail from a single-cell battery. Consider package size constraints and thermal performance within the specified industrial temperature range during design integration.

Battery Management Part Context

This part belongs to the LTC1559 family of battery management ICs. These devices are specialized for maintaining backup power in embedded systems. The CS-3.3 variant specifically targets 3.3V output requirements, distinguishing it from other voltage options within the same functional series.

Battery Management Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the LTC1559 series. Verify that any substitute maintains the same NiCd compatibility and 3.3V output specification.
